3. Introduction
A material that contain one or more organic polymer
of large molecular weight, solid in its finished state, can be
shaped by its flow is called as “plastic”.
According to recent studies, plastic can stay
unchanged for as long as 4500 years and also there has
been a rise in amount of waste being generated daily by
each household.
Plastic waste is used as a modifier of bitumen to
improve some bituminous properties. Plastic roads are
found to perform better compared to conventional
bitumen roads.

7. Scope
The main scopes of plastic roads are economic in terms
of bitumen.
The shredded plastic in form of polymer covers the
aggregates and thus occupies a larger portion of the road
reducing the quantity of bitumen needed.
Waste Plastic is a harmful and non-biodegradable waste
responsible mainly for land pollution.
The lifespan of the road can be increased & Eco- friendly
in nature.

8. Objectives
1) To coat the aggregates with waste plastic material
2)To check the properties of aggregate and bitumen mix
3) To check the properties of aggregate and bitumen mix
due to coating of waste plastic
4) To compare both properties i.e. before & after coating of
waste plastic

10. Processing Details
• Collection of waste plastic
• Cleaning and Shredding of waste plastic
• Mixing of shredded waste plastic, aggregate
and bitumen in central mixing plant
• Laying of bituminous mix

13. Test On Material
• Dry Process
• Plastic waste is collected, segregated and
stored.
• Cleaning of the waste plastic.
• Shredding of waste plastic into the correct
thickness 2.36-4.5mm
• The aggregate is heated to around 160*C-170*C
and then the plastic is added.
• After 30-40s a uniform is observed.

15. Advantages of Dry Process:-
• Plastic is coated over Aggregate – improving
surface property of aggregate.
• Doubles the binding properties of aggregates
• Bitumen bonding is stronger than normal.
• The coated aggregate show increased strength
• As replacing bitumen to 15% higher cost
efficiency is possible
• No degradation of road even after 5-6 years
after construction

16. Disadvantage of Dry Process-
• The process is applicable to plastic waste
material only
• Plastics in the road can break down into
microplastics and can find their way into the
soil and bodies of water.

17. Test On Aggregate
• Flakiness & Elongation Index ( IS -2386-part-I-

34. Plastic waste:-
• Shredding is the process of cutting the plastic
into small sizes between 2.36mm to 4.75mm.
Bitumen:-
• Generally in India bitumen used in road
construction of flexible pavement is of grades
60/70 or 80/100 penetration grade. Both the
grade of bitumen confirming to BIS standards will
be used for the present studies.
Limitations

35. Conclusions
• Plastic will increase the melting point of bitumen. The waste plastic
bitumen mix forms better material for pavement construction.
Hence the use of waste plastics for pavement is one of the best
methods for easy disposal of waste plastics.
• Plastic road would be a boon for India’s hot and extreme humid
climate, where temperature frequently cross 40*C and torrential
rains create havoc, leaving most of the roads with big potholes.
• It is hoped that in near future we will have strong, durable and eco-
friendly roads which will relieve the earth from all type of plastic-
waste
• The use of smoke absorbent material (titanium di-oxide) by 10% of
polymer content can reduce the vehicular pollution.
